' I FLARE-SPLITTER.

" To all whom it may concern Be it known that I, VILLIAM O. Anzmenn,

a citizen of the United States, and a resident of Nashville, in the county of'Davidson and 5 State "of Tennessee, have invented a new and 7 useful. Improvement in- Flake-Splitters,;i;of which the following is aspecification. Myinventionrelates to improvements in flake splitters, more especially those 'de- 10 signedfor splitting the flakesof graphite, in the refining thereof, and it consists inthe combinations, constructions and arrange"- ments herein described and claimed.

\n object of my invention is to provide a device by means of which flakes of graphite during the refining process, "may be split up -so'as to be delivered in very fine condition.

A further object of my inventionis to provide a flake splitter wh ich not only splits-the flakes of graphite but pulverizesany foreign material associated therewith.

A further object of my invention is to provide a device of the type described, which requires relatively little power for its operation, but which will continuously split the graphite delivered to it and will eject it as fast as the splitting operation is concluded.

A further object of my invention is to provide a device of this kind which is very simple in its construction and cheap to manufacture.

Other objects and advantages will appear in the following specification and the novel features of the invention will be particularly pointed out in the appendedfc'laims. My invention is illustrated inthe accompanying drawings forming part of this application, in which:

Fig. 3, is asection through the device showing the exit casing, and Fig. 4c is a perspective View showing the construction of the splitting disks. v In carrying out my invention, I provide a. pair of casingmembersl and 2, respectively, thesefcasing members having outwardly ex- .tendingflanges 3 which are secured togethen by abolt 4 or in any other suitable manner. The'casing members 1 and 2, as will. be observed, are preferably of circular shape and Sp ecificat ion of Letters Patent. v Application filed November 1, 1917. Serial No. 199,714.; i

This disk which is shown atl), has a central opening-1Q into. whiclrtl1e end of the pipe 8 may project.

One rape of this'disk, towi-tnfl t m; to thGOEISlIIg memberl, is'flat as shown-iii" Fig.

1, the opposite face of thedisl'z-yhowever,-is provided with a series ofcurvedteeth 9 These' teeth are constructed in the manner clearly shown in 'Fig. .4. They resemble somewhat, a series of ratchet teeth, the teeth being of greater depth at the outer edge of the disk and narrowing toward the center thereof. The edges of the teeth are curved st in the manner clearly shown in Fig. The casing member 2 is also provided with an integral centrally disposed sleeve 11 arranged to receive the shaft 12 of a motor M, or

other suitablesource of power. It is convenient to use the motor because, as stated, the device requires relatwelylittle power and a motor may be conveniently used when mounted on a platform 13 which may be secured to the casing member 2 as shown in Fig. 1, or may be an independent support.

Secured to the end of the shaft lon the inside of the casingformed by the members 1 and 2',- is a disk 14 which is constructed in a similar manner to the disk 9 already 'described; that is to say, it is provided with teeth l-i similar to the teeth 9 and constructed upon substantially the same curves.

The disks 9 and let havingteeth formed on the same curves, when placed opposite each other, are arranged so'that the curves cross one another or bend in the opposite direo tions from one another; The stationary disk 9 isspaced from the revolving disk 14 atapproxlmately I one thousandth of an inch.
